This invention relates to cosmetic compositions which contain new asparagine derivatives having surface-active properties, and to hair treating compsitions containing them.

US. Pat. Nos. 3,303,213 and 3,331,781 describe and claim asparagine derivatives having very interesting surfaceactive properties, which are of particular use in hair shampoos. We have now found that certain related asparagine derivatives not only show surface activity, but possess other properties which are of considerable interest in relation to the treatment of hair.

The asparagine derivatives used in the compositions of this invention are compounds having the formula:

where R and R are each an alkyl or alkenyl group which has -18 carbon atoms which can be the same or different; R, and R are each lower alkyl, which can be the same or different, or together with the nitrogen atom to which they are attached constitute a morpholino residue and n is an integer of 2-5 inclusive (especially 2 or 3 and sodium, potassium, ammonium and acid addition salts, such as lactate, phosphate, citrate and acetate salts, thereof. Preferred compounds are those in which R, and R are alkyl groups having l4 carbon atoms, for instance methyl or ethyl.

These compounds possess not only remarkable detergent properties, but also good softening and conditioning properties for the hair. Thus they can be used to advantage in hair shampoo or hair dyeing compositions.

Moreover, in acidic aqueous solutions these compounds show a very pronounced thickening and gelling effect. Since products currently employed as thickeners or gelling agents generally do not possess in themselves any detergent or hair treating property, it will be seen that compounds of the invention are particularly advantageous, and because of this combination of properties they have a very wide range of use, for example. in aqueous solutions which may contain other surface-active substances, especially those of cationic or non-ionic character, and in aqueous solutions of dyes.

The compounds of the invention can be prepared by a process which comprises condensing maleic anhydride with an alkylene diamine having the formula:

1 NH (CH N\ R NH where R has the meaning given above. Preferred alkylene diamines are. for example, N-dodecyl-N', N-diethylethylenediamine. N-cetyl-N, N'-diethylethylenediamine, N-dodecyl-N', N-diethyltrimethylenediamine, and ,B-(dodecylamino)ethylmorpholine.

Preferred primary fatty amines are, for example, decylamine and dodecylamine. It has been found that excellent results have been obtained using as primary amine a mixture of fatty amines derived from copra acid or tallow acid, which yield a mixture of coumpounds of formula l differing only in the value of the substituent R, the various R substituents being the various alkyl radicals present in tallow or copra acids respectively.

The invention is illustrated by the following Examples.

EXAMPLE 1 Preparation of the sodium salt of N -[alkyl(tallow)]-N-(dodecyl)-N-(N,N- diethylaminoethyl)asparagine.

l Preparation of N'N-diethyl-N-dodecylethylenediamine There are mixed with stirring 2 moles of dodecylbromide and 10 moles of N,N-diethylethylenediamine (96,6 the temperature being maintained below 50C. At the end of several hours, the reaction is complete. There are then added 4.3 moles of potassium hydroxide in pellet form, with vigorous stirring. The excess of potassium hydroxide and the potassium bromide formed are separated by filtration. The excess of N,N-diethylethylenediamine is thereafter evaporated under reduced pressure, and the crude product thus obtained is washed with water and dried in vacuo on the water bath.

N,N-diethyl-N-dodecyl-ethylenediamine is thus isolated in an almost quantitative yield and in a purity of 98 2 Preparation of N-dodecyl-N-( N ',N diethylaminoethyl) maleamic acid.

One mole of N',N'-diethyl-N-dodecylethylenediamine is dissolved in 300 ml of ethyl acetate.

To this solution is added with stirring, in an hour and a half, 1 mole of maleic anhydride in solution in 300 ml of ethyl acetate, the temperature being maintained between 35 and 40C. The solid which precipitates is separated, washed with ethyl acetate and dried in vacuo, and N-dodecyl-N',N-diethylaminoethyl)- maleamic acid is isolated as a white, water-soluble powder in a yield of 80 3 Addition of the primary amine derived from tallow fatty acids.

0.7 mole of N-dodecyl-N-(N,N'-diethylaminoethyl) maleamic acid is dissolved in 300 m1 of ethyl alcohol, and the solution is neutralized with a calculated quantity of concentrated aqueous sodium hydroxide solution.

There is then added 0.7 mole of a mixture of primary amines derived from tallow fatty acids, and the mixture is heated at C. for 11 hours. After evaporation of the alcohol. the product obtained takes the form of an oil dispersible in water, which contains 4 7! of unreacted primary amine.

EXAMPLE ll Preparation of the sodium salt of N -lalkyl(copra)]-N-(cetyl)-N-(N',N'-diethylaminoethyl)asparagine.

By proceeding in an analogous to Example I. N-cetyl- N-(N'.N'-diethylaminoethyl)maleamic acid is obtained from N',N'-diethyl-N-cetyl-ethylenediamine and maleic anhydride. The desired product is obtained by the addition to the sodium salt of the maleamic acid of a mixture of primary amines derived from copra fatty acids in an analogous way to Example I.

EXAMPLE lll Preparation of the sodium salt of N -[alltyl(tallow)l-N-(cetyl)-N-(N.' l'-diethylaminoethyl)asparagine By the process analogous to that described in Example I, this product is obtained by the addition of a mixture of primary amines derived from tallow fatty acids to sodium N-cetyLN-tN.N'-diethylaminoethyl)malea mate.

EXAMPLE lV Preparation of the sodium salt of N' -lalkyhcopra)LN-(dodecyll-N-(N'N diethylaminoethyl )asparagine This product is obtained by reacting the mixture of primary amines derived from copra fatty acids with sodium N-dodecyl-N-(N.N'-diethylaminoethyl)maleamate in a process analogous to that described in Example l.

EXAMPLE V Preparation of the sodium salt of N -lalkyhtallow)l-N-(dodecyl) N-(morpholinoethyl- )asparagine.

By a process analogous to that described in Example I. there is obtained from dodecyl bromide and aminoethylmorpholine. ,B-(dodecylamino)ethylmorpholine.

The condensation of this diamine with maleic anhydride gives the corresponding maleamic acid which. after neutralization with sodium hydroxide. is reacted with the mixture ofprimary amines derived from tallow fatty acids yielding the desired product in the form of an oil.

EXAMPLE Vl Preparation of the potassium salt of N'--[alkyl(tallow)]-N-(dodecyl)-N(N.N- diethylaminopropyl)asparagine.

N'.N'-diethyl-N-dodecyl-trimethylenediamine is first prepared by a process analogous to that described in Example I. Maleic anhydride is reacted with this diamine in solution in t-butyl alcohol. The maleamic acid thus formed is neutralized by an aqueous potassium hydroxide solution, and the potassium salt is reacted with the mixture of primary amines derived from the fatty acids of tallow. By evaporation of the solvent. the desired product is obtained in the form of a viscous oil.

EXAMPLE Vll Preparation of the sodium salt of N -[alkyl(copra)l-N-(cetyl) -N-(N'.N'-diethylaminopropyl)asparagine This product is obtained by a process analogous to that described in Example VI. It takes the form ofa viscous oil.
